Are there any other means?
What kind of prediction are you dealing with? Is it regression or classification?
What kind of attributes do you have?
I want to predict the count of purchase based on historical data(day, month, salary, expenditure… and finally purchase behavior) . Historical data consists of both numerical and categorical data.
Can regression be done on both numerical and categorical variables at a time?
I am thinking to use probability to solve this problem.
Yes. Dependent variable can be a factor in regression
